This species is uncommon in the Eastern Central Pacific region. Given its restricted range and very shallow, near-shore habitat requirements, it has an area of occurrence estimated to be less than 2,000 km2. This species is threatened by continuing decline in quality and extent of habitat due to extraction, diving, and blast fishing throughout its range. However, it is unclear whether the habitat is severely fragmented. It is therefore listed as Near Threatened. With the availability of further information, this species may warrant listing in a threatened category under Criterion B.
|Range Description:||This species is endemic to the eastern Central Pacific, and is only known from Costa Rica and Panama. The area of occupancy for this species is estimated to be less than 2,000 km2, given its restricted near-shore range and very shallow-water habitat.|
Native:Costa Rica; Panama
|FAO Marine Fishing Areas:||
Pacific – eastern central

|Population:||This species is uncommon, and is rarely recorded despite directed surveys involving appropriate techniques for cryptic species.|
|Habitat and Ecology:||This reef-associated species is found on shallow rocky or coral reefs and in tide pools to depths of five m.|
|Major Threat(s):||Major threats for this species include habitat degradation and destruction due to diving, extraction of corals or live rocks, blast fishing, etc. (Dominici-Arosemena and Wolf 2006). This species may also be susceptible to current or future ENSO events, given its very narrow and shallow depth range (Glynn 1991, Guzmán and Cortés 1992, Hughes et al. 2002, D’Croz and Maté 2004).|
|Conservation Actions:||This species is present in several protected areas within its range. In Costa Rica it is found in Marino Ballena National Park, Isla del Caño Biological Reserve, and Santa Rosa National Park. In Panama it is found in Coiba National Park, Coiba Special Zone of Marine Protection, and Coiba National Park (WDPA 2006).|
